i dont see how gender has anything to do with it the guy was a prick pretty sure if you were a dude manager instead he would have simply said something like maybe if your balls ever dropped youd know how to relax now and then or something i think you took it way too personally he just went with a generic insult about bothering for him behavior same reason a kid might call a black kid nigger not because hes actually racist but just because he knows its the easiest insult to throw that will get the maximum reaction
